The Curriculum Laboratory offers over 25,000 educational materials to support Nursery/Kindergarten - 12th grade curricula. Materials are intended to be used primarily within the lab, although many may be checked out for short periods of time. Textbooks may be checked out for one week. Enrichment materials, CUA (curriculum guides, resource units, and activity books) and IRTS stacks items may be checked out for two weeks. IRTS also maintains a reserve desk of items placed on reserve by faculty.

IRTS textbooks, CUA and stacks collections are arranged in call number order using the Library of Congress Classification System. You can search the holdings we have cataloged via the UNI Rod Library (UNISTAR) system at http://unistar.uni.edu/
